Catching problems early saves money and prevents emergency breakdowns. Watch for these common warning signs.
Banging, squealing, or rattling sounds indicate worn parts, loose components, or ignition problems requiring immediate attention.
Hot and cold spots throughout your home signal ductwork issues, a failing blower motor, or an improperly sized system.
Unexplained increases in your heating costs suggest declining efficiency, dirty filters, or a system nearing end of life.
If your furnace constantly turns on and off, it could mean a faulty thermostat, clogged filter, or overheating heat exchanger.
A healthy flame is blue. A yellow or flickering flame may indicate a carbon monoxide hazard. Call us immediately.
Furnaces last 15-20 years. If yours is aging, replacement can cut energy bills by 30% or more with modern efficiency.

We recommend annual furnace maintenance, ideally in early fall before the heating season begins. Regular service extends equipment life by 5-10 years, maintains manufacturer warranties, and can prevent up to 95% of common breakdowns.
A standard furnace replacement typically takes 4-8 hours and is completed in a single day. More complex installations involving ductwork modifications or system conversions may take 1-2 days. We always provide a timeline before starting work.
Consider replacement if your furnace is over 15 years old, repair costs exceed 50% of a new system, or your energy bills have steadily increased. We provide honest assessments and will never recommend replacement when a simple repair will do.
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. We recommend 90% AFUE or higher for Washington homes. High-efficiency models reach 96-98% AFUE, meaning nearly all fuel becomes usable heat.
Yes! We offer flexible financing options with approved credit, including low monthly payments and promotional interest rates. We also help you identify and apply for all available WA state and federal energy efficiency rebates and tax credits.
We install and service all major brands including Lennox, Carrier, Trane, Rheem, Bryant, Goodman, and more. We select the best equipment for your home based on performance, reliability, and value, not brand partnerships.
Whether you need an emergency repair, a new installation, or simply want to make sure your furnace is winter-ready, Next Phase is here for you.
